We assume that working with the jigsaw needs a certain level of expertise so please take all the precautions related with how the tools work.\n\nWhen cutting with the jigsaw there is danger of overheating and melting the plastic. If this happens some bad fumes could be released. \n\nSpecial attention on plastics like PS and PVC! So in order to work safer make sure to use a gas mask with ABEK filters to prevent inhaling possible toxic fumes. An easy way to identify them is to check if the filter has four colour lines (brown, grey, yellow & green).",

"text": "When selecting the blade several factors have to be taken in account.\n\nType: We prefer using High-Carbon Steel blades (HCS) and High-Speed Steel blades (HSS) for these jobs.\n\nTeeth per inch (TPI): For brittle materials like PS will need a relatively big amount of TPI, around 10-13, in order to allow a safe and clean cut. A smaller amount will make the work faster but rougher.\nFor tough plastics like HDPE and PP we don’t need that many TPI, around 6 is good. An excessive amount of teeth will make it unnecessarily harder.\n\nShape/Blade direction: The blade can point upward or downwards. It produces a smoother cut on the side of the piece that it’s cutting towards. And sometimes in brittle materials can produce chipping on the other side.\nWe recommend to use blades like the ones in the image, where the cutting angle of the teeth is negative or close to zero.

Higher orbital actions will make the job faster and easier but won’t always guarantee a clean cut.",
